Although its current processors are not quite outperforming the ability of these interfaces, Intel Corporation decided recently that it was time to introduce a new package for their flagship Pentium 4 line of processors in order to get ahead of the curve a little bit. The engineers at Intel chose a design that is quite different than any other mainstream CPU available today. The processor design itself has not changed; the packaging of the processor is what has changed. Intel is still using the recently released Prescott core (replaced Northwood) for their Pentium 4 line-up.
